Graphics Card Question

Yesterday I went out and purchased Diablo 3 only to find that my graphics card is apparently too out of date to run the game, according to the "Can You Run It?" website. However I looked at the "Unsupported Video Cards" Sticky Thread posted at the top of the forum and did not see my video card listed. Could someone give me some feedback on this, maybe they just forgot to add it? Or it is under another name on the list. (I really don't know anything about graphics cards, drivers, etc...)

Lastly, assuming my graphics card is not able too run the game, could someone please inform me of maybe a good, well priced graphics card I may want too look into purchasing?
